AI Video Upscaler: Upscale Video to 4K and Rebuild Real Detail
Enhance your video with Topaz and choose an available output size: 1080p, 2K or 4K.
How to Upscale a Video to 4K in 3 Steps
From a soft clip to a sharp one, without leaving the browser
1
Add Your Source Video
Upload an MP4 or MOV file up to 50 MB, or pick a clip you already generated from My Creations. No install, no plugin — it runs in the browser on Windows, Mac and mobile.
2
Choose the Output Resolution
Choose 1080p, 2K or 4K. Sizes below your source are hidden; output dimensions and credits update with your selection.
3
Upscale and Download
Start the job and the enhanced video appears in the history panel when it is ready. Download the MP4 — no watermark, and nothing re-encoded a second time.
Why Choose Our AI Video Upscaler?
Real Detail, Not Just a Bigger File
Stretching a clip in an editor gives you more pixels and the same soft image. Topaz is trained on how real footage degrades, so it reconstructs edges, texture and fine structure instead of interpolating between blurry neighbours — the difference is obvious on a large screen.
Your Edit Survives Intact
Enhance to your chosen output size while preserving the source duration, aspect ratio and editing rhythm.
Compression Artifacts Go With It
Clean up compression artifacts while enhancing detail. If your source already matches an offered size, choose that size for enhancement.
Priced by the Second, Not per Job
Cost scales with the clip you upload, so a six-second social cut costs a fraction of a long one. We measure the real duration on our side, charge whole seconds only, and show the exact figure in the panel before you submit.
Who Uses the AI Video Upscaler?
The footage people bring here is usually soft for a reason — and each reason has a different fix
AI Creators Capped at 720p
Most video models top out at 720p or 1080p. Generate at the model's native resolution, then upscale the take you actually keep — usually cheaper than paying a premium tier to generate large in the first place.
Editors Working From Old Phone Footage
Enhance older phone footage to an available output size so it fits more naturally alongside modern footage.
Social Teams Fighting Re-Compression
A clip that has been downloaded, re-uploaded and re-encoded across platforms carries visible blocking. Rebuilding it before the final export gives the platform a clean master to compress.
Agencies Meeting Delivery Specs
Choose 4K when your delivery requires it, using the source clip and edit you already have.
Streamers and Gameplay Editors
Screen recordings and gameplay capture lose fine text, UI edges and distant geometry to the encoder first. Those hard edges are exactly what detail reconstruction recovers best.
Families Restoring Home Video
Digitised camcorder tape and early digital clips are low-resolution and noisy. Upscaling makes them watchable on a modern television instead of a postage stamp in the middle of the screen.
